Optimized WSN for ECG monitoring in ubiquitous healthcare system

In this paper, we proposed optimized wireless ECG monitoring system with consideration of various factors from ECG in medical practice and wireless sensor network. For same, we introduced ECG data recording scheme and Wireless sensor network model that is efficient in terms of energy and space requirements without affecting the various parameter of ECG. ECG data recoding scheme deal with recording of ECG at different sampling rate, bit resolution and number of leads; that reduce the amount of data for transmission and storage. Wireless sensor network model includes combination of ultra wide band transmit only transmitter and IEEE 802.15.4 transceiver node that supports the high bandwidth requirement and contention free multiple access at hospital environment.
